6 General Information on Vacuum Seam Testing Systems The vacuum test bells were originally developed in the industrial sector for the seam testing of plastic sealing membranes. These devices then found other applications like the testing of plastic or steel containers and plastic or steel tubs. The tightness testing of apparatus and installations using the ventilation method with vacuum bells pertains to the preferred applied tightness test according to information sheet ZfP1 of DECHEMA (Society for Chemical Engineering and Biotechnology). In the industrial sector, the guidelines of the DVS 2225 part 4 para (German Welding Society) are valid. The detection sensitivity of the ventilation method with vacuum bells is between 10-3 to mbar l s-1 and is therefore more exact than tightness testing with liquids or high voltage. For comparison: The detection sensitivity with water, possibly with addition of colouring is approx. 0.5 mbar l s-1, that with petroleum or oil is around 10-1 mbar l s-1. The test method with vacuum is applicable in nearly all cases, even in instances where, for reasons of the stability of the test object, testing according to the positive pressure method is no longer possible. Apart from that, the tightness test dealt with here is a non-destructive material test. The determination of the leakage rate with this kind of tightness test requires further steps. The usual unit used for the leakage rate of gasses is "millibar times Liter per second" (mbar l s-1). Leakage rates in liquids are given, for example, in cm3 s-1 or sometimes g s-1. A leak with a leakage rate of 1 mbar l s-1 exists, for example, if, in the case of an evacuated space with a capacity of 1 l,the pressure per second increases by 1 mbar (prerequisite of constant temperature). To determine the leakage rate, the testing head must be equipped with a tightly closing shut-off device, for example, a ball value on the vacuum connection. Then the test bells are placed on the area to be tested and evacuated as usual. After reaching the testing pressure, the shut-off device is closed and the vacuum pump is switched off at the same time. The time is measured with the closing of the shut-off device. Depending on the size of the leak, the pressure increase will be read off the Manometer in a time span of 10 to 30 s. The capacity of the test bell No. 305 is 8 l in testing state. The specific leakage rate can be calculated from the measured values according to the following formula: L = p V t p = measured difference in pressure in mbar V = content of test bell in testing state (No. 305: 8 l) t = measured time in sec. 6 Technical modifications reserved.

7 Vacuum seam testing systems Vacuum seam testing systems are used for testing any container surfaces and sealings. Thanks to the highly elastic seal, testing of mutually perpendicular surfaces is possible also in the case of minor angular misalignment. A tissue-reinforced PVC hose is available as a connecting piece between the vacuum compressor and the test bell jars.
